The mass transfer coefficient can be calculated using the following equation:
\[k_c = rac{10^{-5} m²/s}{1 imes 10^{-3} m} ot 2 ot (1 + 0.3 ot 100^{1/2} ot 1^{1/3}) = 0.22 m/s\]
These solutions demonstrate the application of mass transfer principles to practical problems. Mass Transfer B K Dutta Solutions
A mixture of two gases, A and B, is separated by a membrane that is permeable to gas A but not to gas B. The partial pressure of gas A on one side of the membrane is 2 atm, and on the other side, it is 1 atm. If the membrane thickness is 0.1 mm and the permeability of the membrane to gas A is 10^(-6) mol/m²·s·atm, calculate the molar flux of gas A through the membrane.
where \(k_c\) is the mass transfer coefficient, \(D\) is the diffusivity, \(d\) is the diameter of the droplet, \(Re\) is the Reynolds number, and \(Sc\) is the Schmidt number. The mass transfer coefficient can be calculated using
Substituting the given values:
where \(N_A\) is the molar flux of gas A, \(P\) is the permeability of the membrane, \(l\) is the membrane thickness, and \(p_{A1}\) and \(p_{A2}\) are the partial pressures of gas A on either side of the membrane. If the membrane thickness is 0
Here, we will provide solutions to some of the problems presented in the book “Mass Transfer” by B.K. Dutta.
